Hello,

I have a very strange error. I recently installed a test environment on my laptop with IIS7/PHP5/MySQL on Vista Home Premium. When I tried to install phpMyAdmin I found that it somehow failed silently, in particular, config file could not get written even though no error was shown. To simplify the situation I set permission as Full Control for Everybody on wwwroot. As I investigated further I found that for some reason when a stream was open the actual file was not written on the disk. For example, the following code

<?php

$fout=fopen('Test.html','w');
echo($fout);echo("<br>fprintf = ");
echo(fprintf($fout,'Hello world'));echo("<br>");
echo(fclose($fout));echo("<br>");
echo($fin=fopen('Test.html','r'));echo("<br>fscanf = ");
echo($ftext=fgets($fin));echo("<br>");
echo(fclose($fin));echo("<br>");
echo(getcwd());

?>

Produces output

Resource id #2
fprintf = 11
1
Resource id #3
fscanf = Hello world
1
C:\inetpub\wwwroot

However, if I navigate to the directory

the Test.html does not exist.

When I modified the code to be

<?php

try{

	$fout=fopen('Test.html','w');
	echo($fout);echo("<br>fprintf = ");
	echo(fprintf($fout,'Hello world'));echo("<br>");
	echo(fclose($fout));echo("<br>");
	echo($fin=fopen('Test.html','r'));echo("<br>fscanf = ");
	echo($ftext=fgets($fin));echo("<br>");
	echo(fclose($fin));echo("<br>");
	echo(getcwd());echo("<br><br><b>Contains:</b><br><br>");

	$handle = opendir('.');
    while (false !== ($file = readdir($handle))) {
        if ($file != "." && $file != "..") {
            echo ($file);
			echo("<br>");
        }
    }
    closedir($handle);

}
catch (Exception $e) 
{
    echo 'Caught exception: ',  $e->getMessage(), "\n";
}
?>

The file appeared in the directory. When I moved helloWorld.php (the php file I was using for testing) to phpMyAdmin folder I got wrong address error, but when I removed index to browse all files in folder I found it. Once I saw it in the folder it ran fine even after I returned the index. phpMyAdmin configuration still doesn't work though (file doesn't get written).

This makes me think there is some weird cache problem.. but I can't figure out how I can fix it. I looked at IIS manager and nothing jumps out.
